The word(s) "fault" appears 36 time(s) in 35 verse(s) in Quran in Muhammad Habib Shakir translation.

(31) So know that there is no god but Allah, and, ask protection for your fault and for the believing men and the believing women; and Allah knows the place of your returning and the place of your abiding.

(32) That Allah may forgive your community their past faults and those to follow and complete His favor to you and keep you on a right way,

(33) O you who believe! let not (one) people laugh at (another) people perchance they may be better than they, nor let women (laugh) at (other) women, perchance they may be better than they; and do not find fault with your own people nor call one another by nicknames; evil is a bad name after faith, and whoever does not turn, these it is that are the unjust.

(34) He will forgive you your faults and cause you to enter into gardens, beneath which rivers flow, and goodly dwellings in gardens of perpetuity; that is the mighty achievement;

(35) He will forgive you some of your faults and grant you a delay to an appointed term; surely the term of Allah when it comes is not postponed; did you but know!
